I have developed a Qt application that communicates with a specific bluetooth device. The application works on linux, android and mac flawlessly, but the qbluetooth api is not supported on windows. I have selected the serial api as a workaround, and have successfully done the task using a virtual COM port on the bluetooth device. The problem is that I don't want the end-user to create the COM port, and want to create it in setup time programmatically. I have done an extensive search, but have found no clue on it. Can anyone give me a hint on it? Thanks in advance.

To make my program could communicate with Nokia phone I have setup libusb-win32 library. But after I have this library installed any standard Nokia soft like PC Suite refuses not only to communicate but even to detect my phone! The phone is still available only to my program through libusb-win32 now. Removal of the libusb0.sys driver helps and phone becomes again accessible through Nokia PC Suite, but then it is no more visible to my app via libusb-win32 library. Whether it is somehow possible to get the phone accessible as through libusb-win32 for my application as for standard Nokia phone programs (Nokia PC Suite, NSU, NSS, etc.)?
I run Windows 7 Enterprise and libusb-win32 1.2.6.0
Answer to myself. Yes, it is possible. The driver libusb-win32 should be installed in the filter drive option, not in the device file option.
I'm manufacturing a device that connects to my computer using Bluetooth and then a desktop Java app uses the Bluetooth connection to send serial data to the device which is then displayed.
When I try to connect my device to windows 7 it successfully finds and pairs with it creating a Bluetooth link on a COM port. This link can then be used by a serial prompt (used for testing) or my Java application. It works initially however soon after windows drops the connection and the only way to reconnect is to delete the device within devices and printers and then reconnect.
This seems to be a known problem with windows bluetooth so I decieded to use a third party Bluetooth application. I downloaded and tried Toshiba's Bluetooth Stack and it was able to add a Bluetooth device and keep a stable connection which works great however this only works for Toshiba computers without getting a cracked version.
This device is commercial and can't be sold with cracked versions of software. Has anybody experienced the same problems or not in other operating systems and has any solutions of advice as that would be a tremendous help.
This is not a good idea/method to use the COM ports generated by Windows, it's not working fine and not reliable in any scenario ; you should use Bluetooth Sockets instead.
Using Toshiba or Widcomm or BleuSoleil won't help: under Win7, all dongles are now trying to use the Microsoft Stack, not their own implementation.
I want to capture distances from sensors, using an Arduino and a Windows Phone device. How can I do that?
The Windows Phone 7 SDK does not give access to the USB port or Bluetooth on the phone, so you can't use that. So I think the best way (and probably only way on Windows Phone 7) would be to communcate over Internet or local network with the Arduino acting as a server which the Windows Phone 7 app connects too.
Here are some examples of an Arduino web server and TCP server.
For the Windows Phone client I would check out either WebClient or sockets.
Windows Phone 8 SDK:
Consider establishing an App to Device communication through Bluetooth API which became available for developers in the release. Bluetooth App to Device application sample, available on MSDN, is the way to go.
There is another option in Windows Phone 8, using Proximity (a set of classes which works with NFC), which is more applicable for a short range communication.
As for Arduino, there is certainly a Bluetooth module.
Windows Phone 7 SDK:
No way to establish a peer-to-peer communication with a third party device. A workaround would be to connect them through a network, as was proposed by Johan.
I have actually made a Windows Phone 8 App that connects to an Arduino using the Sparkfun Bluetooth Silver Modem. Issues is, even after I get them connected, I can't get either the Arduino to receive the input OR I can't get the WP8 App to successfully send to the Arduino...
My GitHub for the project is: https://github.com/lanceseidman/Arduino-Bluetooth-WinPhone8
Hoping everyone can try and help on the project.
My Breadboard photos will be up soon and my Arduino Code.
I would like to make a Windows Phone 7 application that takes advantage of it's USB port to communicate with the PC. I would like to write an application to control or push information/data to the PC from the application. But I am having problems finding information on where to start. Can anyone help point me in the right direction with some resources?
The only way to communicate over the USB connection is over HTTP.
To get this to work you'll need:
- a webservice hosted on the PC you're connecting to.
- a way for the app (on the phone) to know the hostname of the PC. (You'll probably need to enter it manually)
When you have these it should be straight forward.
You can't.
If you want to make sure to push data to a client PC, you will have to use a kind of synchronization by using the internet. For example create a wp7 application and a desktop application and let them sync the data based on a user object or anything like that.
As far as I know also the updated SDK for Mango will not support programming against the USB dataconnection.
In Short: I need to detect hotplug events of my USB CDC device by PID/VID and get the corresponding virtual COM port which was created by Windows in Visual C++ and in the end create a dll.
I have a USB CDC device which I need to be notified of when connected/disconnected on Windows. My approach is to use RegisterDeviceNotification and an "invisible" Window to receive WM_DEVICECHANGE notifications. This part is working so far.
Now as far as I found out I need to get the list of USB devices that is plugged, iterate over it and filter out the devices with my PID/VID? I assume that I am then able to get more informations about the device including the COM port?
Is the only way to achieve my goal to use SetupDi calls in setupapi.h? Is using WDK / DDK the only way to achieve my goal?
As soon as that is working I open-source it on http://github.com/vinzenzweber/USBEventHandler. The Mac version is available already!
After digging through tons of useless documentation at msdn and some debugging I found the missing link: SetupDi calls in setupapi.h: More infos as well as source code for Mac and Windows can be found in my USBEventHandler project at github.com with sources for Mac and Windows.
